WALLACE GALREY THOMSON, OF SELBY, ENGLAND.

FLOOR-CLOTH MACHINE.

SPECIFICATION forming part of Letters Patent No. 619,634, dated February 14, 1899.

Application filed August 5, l 8 9 8.

To all whom it may concern.-

Be it known that I, WALLACE GALREY THOMSON, residing at Selby, in the county of York, England, have invented certain new and useful Improvements in Linoleum or Floor-Cloth Machines, of which the following is a specification.

This invention relates to machines for making inlaid linoleums and other floor-cloths; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a cross-section through the machine. Fig. 2 is a side View with some of the parts removed and broken away for clearness. Fig. 3 is an end view showing the feed-hoppers. Figs. 4 and 5 are cross-sections through one of the linoleumcontainers, taken on the lines 1 2 and 3 4., respectively, in Fig. 6. Fig. 6 is a longitudinal section through one of the linoleumcontainers. Fig. 7 is a plan View of the same. Figs. 8 and 9 are detail side views showing the means for operating the table in the raised and lowered positions of the table, respectively. Figs. 10 and 11 are respectively an end view and a partial side view of the stripping mechanism. Fig. 12 is a side View of one arm G and one stop K and their operating devices, showing also one container in section and the various parts cooperating with it. Fig. 13 is a detail cross section through one of the rollers D. Fig. 14 is an end View of one container and the mechanism for operating it. Fig. 15 is a detail side View of the connections between one of the rods M and the collecting-bars. Fig. 16 is a front view of one of the containers, showing its supports and the means for operating it.

A is a frame of any approved construction, and G is a main shaft carried by brackets H secured to the frame.

M is the driving-shaft of the machine, journaled in the lower part of the frame and revolvedbyanyapproved means. (Notshown) V is an external toothed wheel carried by the main shaft and driven by a toothed pinion V, carried by the driving-shaft.

V is an internal toothed wheel formed integral with the wheel V.

U are toothed wheels secured on shafts U, journaled in the frame A. The wheels U are Serial No, 687,861. (No model.)

arranged in aseries equidistant from the main shaft, and they gear into the wheel V L are cams secured on the shafts U for operating the containers.

The containersB are arranged in a series on a curve and are slidable radially of the main shaft, as shown in Fig. 1. As the containers and the collecting and depositing mechanisms cooperating with them are all alike, the description will be confined to one of them, as shown in Fig. 12.

The container has slides L at its ends, which are slidable radially in guides L, secured to the frame A, and are moved toward the shaft by a cam L and away from it by springs L or by gravity. (See Fig. 1.)

Each container holds a different color of linoleum in the form of paste, and the ma: terial is introduced through the hopper O at one end of the machine.

D is a screw conveyer journaled in the lower part of the container, and d is its shaft. Above the conveyer is a roller D, the shaft 01 of which is journaled in bearings at the ends of the container, (see Fig. 6,) and D are three longitudinal slots formed in the roller. D are spring-pressed bars which slide radially in the said slots, and D are knives mounted on the said bars and forming the molds for the tesserze or cubes of linoleum.

E are the springs, interposed between the shaft 01 and the ends of the bars, and E are guide-pins for the springs. The end portions of the container have recesses eand E at the top and at one side, respectively, and the springs project the bars into these recesses when they come opposite to them.

F is an opening at the top of the container, and f is an opening at its side. The plastic material is forced by the screw conveyer into the molds when the said molds are opposite the conveyer. The conveyer is driven by a toothed wheel F on the end of its shaft, which gears into the wheel U. (See Fig. 14..) The wheel F gears into a toothed wheel F, mounted on a pin which projects'from the end of the container, and the wheel F drives the toothed segment F mounted concentric with it. The toothed segment gears into a toothed wheel F on the shaft (1 of the roller D, and when the said roller has three slots the parts are so proportioned that it revolves one-third of a revolution and then stops while the conveyer is turning the remaining portion of the revolution. This enables the conveyer to pack the material into the mold presented to it.

The tesserae are removed for use in making floor-cloth when the mold projects at the opening at the top of the container, as shown in Fig. 5. The superfluous tesserze not then removed are discharged from the mold by a toothed scraper E when the mold projects through the opening f and are disposed of in any convenient manner.

The tesserze required for use are collected and removed by a series of arms G, pivoted on the main shaft G and provided with needle-points G at their free ends. When the arms are placed opposite the mold, which projects at the top of the container, the cams Lmove the container toward the shaft, so that the tessera: are impaled on the needle-points. The wheel F is moved out of gear with the wheel U by the cams L, so that the roller D is not revolved while the tesserze are being impaled, and the roller does not recommence to revolve until the continued motion of the cams L permits the springs to draw back the container to its'original position. Each impalement arm is operated by toggle-levers H, pivoted to its upper end, a spring H, and a rod B connected to the joint of the toggle-levers. The spring H is carried by a cross-piece and arms H secured to the brackets H The rod B is operated by a bell-crank B pivotally-supported by the frame and moved back by a spring 8. The bell-crank is moved forward and controlled by a part B of an extra harness attached to a jacquard mechanism similar to that of a loom. This jacquard mechanism (not shown) is of any approved construction and is preferably supported above the floor-cloth machine and is operated by a crank Y on the driving shaft and a connectingrod Y. (See Fig. 2.)

K is a slidable stop-finger which is projected into the path of each arm when it arrives in front of the tessera to be impaled on it. The stop-finger is guided in any approved manner and is operated by a bell-crank K, pivotall y supported by the frame A. The bellcrank is moved to retract the finger by a spring 70, and K is a part of the ordinary harness of the jacquard mechanism, which is connected to the said bell-crank and which operates to project the stop finger at the prearranged time. All the impalement-arms are operated and controlled by the jacquard mechanism in a similar manner, and the ordinary pattern-cards of the jacquard mechanism cause the impalement-arms to select and transfer tesserze of diiferent colors and enable the floor-cloth machine to make linoleums having designs similar to those of Axminster and other carpets. The harness is guided by any approved means, such as guides or guide-bars K as shown to the left in Fig. 12.

M are collecting-bars extending across the machine and pivoted to the shaft G by arms M. These bars pass through curved slots M in the frame. These bars collect all the impalement-arms and bring them to a vertical position after they have impaled the tesserae. The collecting-arms are operated by rods M and have their upper ends pivotally connected with the upper ends of the said rods by links M". (See Fig. 15.) The rods M are raised and lowered periodically by cams M secured on the driving-shaft, as shown in Figs. 2 and 12.

N is the table, which supports the textile backing P under the impalement-arms when vertical. The backing P is carried by a reel W and is fed through the machine by any approved mechanism for that purpose.

The table N is carried by a shaft N, the ends of which are guided in curved slots N formed in blocks N which slide horizontally in guides N on the frame. The table is raised intermittently by cams B, secured on the driving-shaft. These cams operate on rollers R, carried by the lower ends of rods R which are pivoted to the table, as shown in Fig. 11. When the table is being raised, the blocks N are held stationary, and the curvature of the guide-slots constrains the table to move laterally toward the suspended tesserae, thereby bringing the last row of tesserae (see Fig. 12) into close contact sidewise with the row of tesserze carried by the impalement-arms and ready to be deposited on the backing.

S is a toothed stripping-comb carried by arms S which are pivoted to the ends of the table. These arms are operated by cams S, secured on a shaft S, which is journaled in the frame A. The shaft S is revolved by a toothed wheel 8*, which is connected with a toothed wheel S on the driving-shaft by means of an idle-wheel 8. When the table is raised, the stripping-comb is brought to the position shown in dotted lines in Fig. 10, so that the tesserae are stripped off the needle -points when the table descends and are deposited on the backing.

The table is preferably constrained to descend vertically, so as to prevent possible injury to the pattern, by means of cams T, which are secured on a shaft '2, journaled in the frame and extending crosswise under the table. (See Fig. 2.) The shaft tis driven by a toothed wheel i, which gears into the internal toothed wheel V and the cams engage with rollers T, mounted on pins projecting from the ends of the table. The cams move the sliding blocks horizontally while the table is descending, so that the curvature of the guide-slotsis neutralized and the tessera: are stripped ofi the needle-points without being moved laterally. When the canvas backing has received the tesserze, it may pass direct to a finishing-machine of any approved construction. 4

The action of the machine is as follows: The plastic linoleum from the hoppers is pressed into the molds as the latter pause over the conveyers, and the molds containing the tesserze are subsequently protruded at the upper part of the containers by the springs carried by the rollers D. The jacquard mechanism and harness operate to bring the impalement-arms over the tesserze, according to the number and color of them required. The containers are then raised, so that the tesserze are impaled and the containers are lowered. The collecting-bars then assemble the impalement-arms in a vertical position over the table and the table is raised. The stripping-comb is moved over the tesserze, so that they are deposited on the backing as the table descends, and the cycle of operations is recommenced after each deposit of tesserae.
